Abstract

PROBLEM TO BE SOLVED: To surely engage a fishing line with an engaging part for the fishing line in the engaging part for the fishing line provided in a spool of a spinning reel. SOLUTION: This spool of the spinning reel is provided with the engaging part 70 for the fishing line L rearwardly protruded and formed into an annular shape so as to be concentric with a spool shaft 15. A groove part 71 is formed in the peripheral direction of a protruding part around which the fishing line L is wound in the engaging part 70 for the fishing line L by, e.g. cutting working. The fishing line L is prevented from slipping off by the rear wall part of the groove part 71. In this case, since the engaging part 70 for the fishing line L is protruded to the rear of a line winding drum 7a and integrally formed, the engaging part 70 for the fishing line L is readily formed. The fishing line L can surely be engaged with the engaging part 70 for the fishing line L by winding the fishing line L around the groove part 71 of the engaging part 70 for the fishing line L.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool of a spinning reel and, more particularly, to a fishing line locking portion for locking a winding start end of a fishing line wound on the spool.

[0002]

2. Description of the Related Art A spinning reel generally includes a reel body rotatably supporting a handle, a rotor, and a spool. The spool of the spinning reel is freely movable back and forth with respect to the reel body, and a bobbin trunk on which fishing line is wound, a large-diameter flange disposed at the front end of the bobbin trunk, and integrally with the back of the bobbin trunk. And a formed skirt portion. The flange portion is fixed to the bobbin trunk by a flange fixing member. A fishing line locking portion for locking the winding start end of the fishing line wound around the bobbin trunk is provided on the inner peripheral side of the bobbin trunk.

[0003] Such a fishing line latching portion locks the fishing line winding start end on the inner peripheral side of the bobbin trunk to facilitate the winding of the fishing line around the bobbin trunk. As disclosed in, for example, Japanese Utility Model Publication No. 4-13972 and Japanese Utility Model Publication No. 30222320, this fishing line locking portion is provided separately from the bobbin trunk and buried on the inner peripheral side of the bobbin trunk. The fishing line is locked by winding and tying the fishing line around the locking pin.

[0004]

Since the conventional locking pin is provided separately from the bobbin trunk, when the locking pin is mounted, a process such as press-fitting, bonding, insert molding, or the like is performed. Is necessary, it is troublesome and troublesome. Therefore, it is conceivable to integrally form the bobbin trunk and the locking pin portion and post-process the locking pin. However, this type of locking pin is provided on the center axis (ie, spool axis) of the bobbin trunk.
In many cases, it is formed at a position eccentric to the center. For this reason, when post-processing the locking pin, it is difficult to form the locking pin.

Further, when the locking pin is formed by injection molding of a synthetic resin, it is necessary to taper rearward for die-cutting. When a taper is formed in the locking pin, the fishing line is easily pulled backward. An object of the present invention is to provide a fishing line locking portion for locking a winding start end of a fishing line wound on a spool of a spinning reel.
An object of the present invention is to easily form a fishing line locking portion.

Another object of the present invention is to make it possible to reliably lock a fishing line at the fishing line locking portion.

[0007]

A spool of a spinning reel according to a first aspect of the present invention is a spool of a spinning reel that is movable back and forth with respect to the reel body, and includes a bobbin trunk around which a fishing line is wound, and a bobbin trunk. A skirt portion formed at the rear end of the bobbin trunk and having a larger diameter than the bobbin trunk, and an annular fishing line protruding rearward from the rear end of the bobbin trunk on the inner peripheral side of the skirt and integrally formed with the bobbin trunk. It has a locking portion and a fishing line insertion portion formed through the front end of the skirt portion.

In such a spool, the fishing line locking portion is
The bobbin trunk is formed integrally with the bobbin trunk so as to protrude rearward from the rear end side and is concentric with the bobbin trunk. Here, the winding start end of the fishing line is locked, for example, by winding it around a protruding annular portion of the fishing line locking portion. Then, the tip of the fishing line is inserted into the fishing line insertion portion formed at the front end of the skirt portion, and the fishing line led out to the outer peripheral side of the bobbin trunk is sequentially wound around the bobbin trunk. In this case, since the fishing line locking portion is integrally formed so as to be concentric with the bobbin trunk portion, the process is simplified, and the fishing line locking portion can be easily formed.

A spool according to a second aspect of the present invention is the spool according to the first aspect, wherein the fishing line locking portion has a groove formed along the outer periphery. In this case, by winding the fishing line around the groove formed in the circumferential direction, the fishing line can be securely locked. A spool according to a third aspect of the present invention is the spool according to the first or second aspect, wherein the fishing line engaging portion is formed so as to have a shape that widens toward the rear.

In this case, the fishing line catching portion has a shape that widens toward the rear, so that it is difficult for the fishing line to fall backward. A spool according to a fourth aspect of the present invention is the spool according to any one of the first to third aspects, wherein the fishing line insertion portion has a through hole formed in the skirt portion, and a guide portion attached to an inner peripheral edge of the through hole. I have.

In this case, since the guide portion is mounted on the inner peripheral side of the through hole, the through hole is less likely to be damaged even if the fishing line abuts and rubs. A spool according to a fifth aspect is the spool according to the fourth aspect, wherein the guide portion is made of hard ceramic. In this case, for example, by using hard ceramics having low friction, the fishing line can be smoothly led out.
